Device for location of interference noises within vehicle has control unit that carries out comparison of determined noise value with the data of first and/or second memory unit

摘要

A data is stored a three dimensional representation of the object in a first memory unit (3D) and/or a normal noise value of the object is stored in a second memory unit (NG). The noise values of the object to be tested obtained from the acoustic sensors (M1-M4) are stored in a third memory unit (SP). A control unit (SE) carries out a comparison of the determined noise value with the data of the first and/or second memory unit.
